一旦獲得了滿意的潤滑系統，相互作用的元件的硬度就成為緊要之事。 -
Traditionally, pump manufacturers have specified hardened martensitic stainless steels for critical wear parts, maintaining a 50 - 100 brinell hardness difference between rotating and stationary components as experience has shown this is adequate to prevent galling
通常，製造商採用特殊的淬火馬氏體不銹鋼製造關鍵磨損件，旋轉件和固定件的布氏硬度分別保持在50 - 100 ，經驗表明，足以防止發生咬合現象。 -
Then because the real operation temperature of the tube is the critical factor for predicting the tube lifetime, we heat some unused tubes in the lab. then we measuer the rigidity of them and find the relationship between the hardness and heat - intensity parameter
其次，由於管件的真實使用溫度是預測其壽命的關鍵因素，因此，本文通過對未用管材按照幾種不同的加熱規范在實驗室進行模擬加熱，測定其加熱后的硬度，找出顯微硬度與熱強參數的關系。
